Specification forming part of Leti ers Patent No. 6,33l dated November2, 11569,v

To all whom it may concern:

Be it known that I, GEORGE LITTLE, of

RutherfordlPark, in the county of Bergen and State of New Jersey, haveinvented and made a new and useful Improvement in Telegraphic Apparatus;and I do hereby declare the fol-4 lowing to be a full, clear, and exactdescrip- Y tion ot' the said invention, reference heilig had to theannexed drawing, making part of this specification, wherein- Figure l isa plan, showing the magnets and paper previous to and to be employed invtransmitting said communication. I make .use of an insulatedcircuitcloser, over which '-a spring is caused to move by the action ofa key, that also turns the cylinder to give motion to the paper. Theinsulated circuit-closer is so formed, with metal bars and interveningnon-conducting material, that the proper pnlsations of electricity aregiven.

The electricity acts on one magnet to give the power necessary formoving the perforating-punch by means of a lever, and at the saine timea second` magnet clamps the feed to hold. that still while the papelgisbeing perforated. The movement of the armature and lever for punchingthe paper simultaneously operates a circuit-changer, that throws thecurrents from the first and second magnets through a third magnet, thatacts to raise the punch, so that it cannot remain through the paper, andthis last action again changes the switch so that another pulsationcannot pass through the third magnet until the electricity again passesthrough the rst magnet. Thus, the rapidity of the perforating operationis only limited by the speed of the electrical current andthe inertia ofthe parts.

In the drawing, a is the frame ofthe machine carrying the shaft b, onthe end of which are the feeding-disks c, that are turned with the saidshaft b, by spring friction-plates d. The vertical rods e, passingthroughthe frame a, calry the cross-piece el, that presses the papertothe disks c by the action of the springs 2 2, the force being adjustedbythe nuts 3. `0peningsare formed through the side portions o't' thecross-piece el, and the paper passes through them and between thecross-piece e1 and the lower portion e2, that carries, in the middle,the die e3, for the punch. Above thev cross-piece el are the studs 5 and6, oneof which recei'vejs the fulcrum-pin 4 of the lever f,fthe otherguidesl said lever, and,

by a nut,.limits the movement vof said lever;

and at one end of this lever is thearmature g of the magnet h, and attheother end the armature 7c of the magnet l",- v and this lever f' actuates the punch a, shown by dotted lines in-Fig.'2. The die e3 of thepunch is supported by the portion e2. The magnet lt causes the punch ato perforate the paper, and it also moves the lever circuitchanger m,the endI thereof' moving from the non-conducting block 7 to theinsulated conducting-block 8. This lmovement directs the electricalcurrent from the frame of the machine through the magnet l, in orderthat the saidniagnet l may raise the punch instantly out of the paper.The pulsations of electricity are given through the key or mechanismhereafter described, and at the time the magnet h is'changed, and thepaper is beingpunched, the feed o't' the paper is momentarily arrestedby thepins m1 that are in the poles of the magnet m2, and, g

being magnetized atthe same time as the magnet h, attach themselves tothe sides of the disk c, holding them, but the frictional connection dto the shaft b allows that shaft to continue to revolve. The means forgiving the electrical pulsations consist of a range of keys, a3 a3, thevsame being extended to any desired length, and operating in connectionwith the shaft b. The arrangement of letters, figures, or signs, 0n theinger-keys, and the groups of conductors and non-conductors, tov

produce the proper pulsations and intervals vfor theyarious telegraphiccharacters, being of any-usual or desired character, do not require tobe described. l will proceed to describe one ofthe 1in ger-keys, theybeing alike, except asto the arrangement of the alternate conducting andnon-conducting surfaces and spaces. The cylinder o, on the shaft b, is

PATENT OFFICE.,

made of non-conducting material, having l grooves` 9 therein,between theribs 10. The

circuitcloser p is in the form ot a segmental block occupying the groove9, and vformed with non-conducting portions 11 between -the Vbars 12,that are united to the metal body of said circuit'closer, and, by themetal. arm 13, connected with the bar g, which forms part ot' the frameof the machine. In shallow grooves `in the cylinder o, at the sidesofthe groove 9,

is a clamping-band, s, that is open on the upper side so as to giveaccess freely to the circuit-closer p. This band s has, near one end,ears, receiving the fulcrum14 ot' thc key a3. the end of which passesinto the other end ot' t-he band s, so that the pressure on thefinger-key n? first tig itens the band s, clampY ing the cylinder o, andcausing it to be rotated bythe depression of the finger-key untilarrested by a properly-placed stop, r, taking against the bart, that isinsulated from the rest of the frame ofthe machinebut put intoconnection with the band s4 by .the tlexible metallic strap u. The bands carries a springI l finger, c, that runs over the circuit-closer as.

the key n3 and` band s are moved, and causes the circuit to be openedand closed.A And I remark that tlze shaft b, being turned with thecylinder 0, and feeding the paper between the respective pulsations thedistance between the end of the finger 'u' and the tirst bar 12,determines the space that the paper is n10-ved before being perforated.When the fingerkey is released the contractile rubbcr-spring w draws theband s back to its normal position. The stop 18 arrests the furthermovement. The band s expands su'iciently to lift the end of the finger vclear `of the circuit-closer, upon the return movement. The wire 30leads from onepole of the battery to the `binding-screw 31. -The otherscrew. 32, is

connect-ed with the opposite pole of the battery. From 32 is a Wireconnecting with the magnet h, and a branch to the magnet l. From 3l awire connects with the bar q and frame of the machine, so thatpulsations ot' electricity can pass from any part of the frame a or q.When a finger-key is operated, such pulsations pass along the arm 13,circuitcloser p, and spring fu, to the band s1 (insulated by thecylinder 0,) by the stop 1", to the insulated bar gt, thence through themagnets m2; y and h to the binding-screw 32. C The pulsation` ot'electricity only passing when one ot' the bars, 12, isin contactwith thespring c, this" circuit is therefore instantly broken bythe movement;but the movement of the armature gand lever f has caused the punch topertbrate' the paper, and alsol thrown the V leverm up, with its end incontactwith the insulated connection 8, to the magnet l, so that theelectricity, passing from the frame a, through m, 8, and l, back to thescrew 32,

causes the magnet l to draw down the armature 7c, lifting the punchandrestoring the parts to their normal positions, andy breaking thecircuit through Z, by bringing the. lever m` into the position shown inFig. 2. The direction of the current may be changed by reversi ing thebattery-wires, the operation being the same. y The punch might bewithdrawn by a spring or permanent magnet, but I prefer theelectro-magnet shown.

.What I claim, and desire to secure by Letters Patent, is j 1. Thecircuit-closer p in the cylinder o, in combination with the band s,

key n3, and linger fv, substantially as and for` the purposes set forth.

2. The feeding-disks c on the shaft bof the cylinder o, in combinationwith the frictional `connection d and holding-magnet m2, for

moving the paper by the direct faction `of the cylinder o, and arrestingthe-'movement of the paper when the punch is acting, substair tially asand for the purposes set forth.`

3. The'magnet L, in combination withV the magnet h, lever f, punch n,and circuitchan ger m, for pertbrating the paper, and then drawing backthe punch by magnetism, substantially as set forth. l f 4. Thecircuit-changer m, in combination with the magnets h and Z and lever f,to di- 'ecththe electric current, substantially `as set ort In witnesswhereof I have hereunto set my i signature this 7th day of April, 1869.
